In my opinion, Paysera is presently not taking registration of Indian Citizens. However, you can check whether it takes registration in your case.
If Paysera is a payment gateway and works like Paypal then you can use the same.
Further, if the EU allows for opening a business account without any business presence, you can open the account.
Kindly ensure you transfer all the foreign remittances received in that account to India.
Because, as per your residential tax status, you will have to pay tax on all your income earned during the FY in India.
Further, if you directly receive the payments in Paysera or Paypal, you do not have to worry about any taxes in that country because you will receive them in India.
